Ineed this anwser asap the distance time graph for four objects is shown below: which object is moving at constant speed? object a object b object c object d

Hey !

The anwer is : A.

Because an object is moving at constant speed ( whic is distance/time) when the distance and the time grow directly proportional . (it means when the distance is getting bigger,then the time is getting bigger equally).

The formula for speed is:

Where x is the 'rise' and t is the 'run'. If x is growing faster for every interval of t, it means that the speed is increasing. The only way this can happen is if x has exponential, cubic or quadratic growth.

Because you need constant speed, your answer is the line with the constant slope, or Object A.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
